Abstract: Apparatus for removing a printed circuit board (PCB) and bezel assembly from a unit includes a pull spring is attached to opposing sides of the PCB and bezel assembly. Each pull spring includes a generally M-shaped spring. A first end of the M-shaped spring includes a first pin carrying a knob. The first pin extends through an opening in the bezel and the knob is disposed within a recessed portion of the bezel and is generally flush with a front face of the bezel with the M-shaped spring compressed in a normal constrained position. In an extended position when the M-shaped springs return to a substantially uncompressed state, the knobs are pushed forward and are spaced apart in front of the bezel, enabling a person to grip and pull each knob to remove the PCB and bezel assembly from the unit in which it is installed.

Abstract: A connector retention apparatus for resiliently retaining connectors of different heights in mated engagement with a device. Included in the apparatus is a base assembly adapted to be connected to a device; and, at least a resiliently deflectable assembly connected to the base assembly and including a connector engaging portion that is biased for engagement with a connector and capable of accommodating and biasing connectors of varying heights into mated engagement with a device. A card and connector retention system for retaining a printed circuit card assembly to a device and a connector to the printed circuit card assembly. The system includes a connector assembly for retaining a printed circuit card assembly to a device; and, a connector retention apparatus for resiliently retaining connectors of different heights in mated engagement with the printed circuit card assembly. The connector retention apparatus is couplable to the connector assembly. A method of assembly is also provided.

Abstract: A release latch includes a latch mechanism. The latch mechanism has a base, and an arm. The arm has one end attached to the base, and a free end. The latch mechanism further has a catch connected to the free end of the arm. The base is adapted to be attached to a first component, and the catch is adapted to releasably engage a second component to releasably hold the first component against the second component. The release latch further includes a release mechanism adapted to be attached to the first component, and being movable relative to the base. When the release mechanism is moved, the release mechanism engages the arm to move the arm, thereby causing the catch to disengage from the second component and allowing the first component to be moved away from the second component.

Abstract: An electronic system contains a backplane circuit card assembly for distribution of electrical signals to one or more modules. The card assembly includes a plurality of pluggably connected base cards, which provide redundant function. Preferably, two base cards in a single plane are connected by a single smaller parallel offset jumper card, the cards being coupled by pluggable connectors. The system preferably includes redundant power supply modules and redundant functional modules, which plug into the backplane from both sides. The modules connected to any one of the base cards provide minimum system functionality in the absence of the other card and its modules. Due to the redundant function, it is not only possible to replace any module, but is possible to replace a base card itself, while the system remains operational. The exemplary embodiment is an intelligent redundant array of independent disks (RAID) storage server having concurrent maintenance capability.
